Description

Technical Field

[0001] This invention relates to the field of real-time road condition monitoring technology, and in particular to a smart traffic real-time road condition monitoring device. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in car ownership, traffic congestion and accidents are becoming increasingly serious, which puts forward higher requirements for real-time monitoring and management of traffic conditions. At present, traffic monitoring equipment mostly uses fixed cameras for road condition monitoring, which cannot flexibly cope with changing traffic conditions.

[0003] To address the aforementioned issues, a search revealed Chinese patent application number CN202411187824.4, which discloses a smart traffic real-time monitoring device. This device collects data such as traffic flow, vehicle speed, and vehicle type through a monitoring structure and image acquisition device. The collected data is then fused and integrated by a real-time traffic monitoring and comprehensive analysis and early warning system to obtain more comprehensive and accurate traffic information.

[0004] However, the above-mentioned technical solutions lack a mechanism to adjust the height and shooting angle of the camera when congestion occurs, which results in the inability to quickly identify the source of congestion and thus slow traffic congestion handling efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smart traffic condition real-time monitoring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart traffic real-time monitoring device includes a set of mounting columns fixed to the top outer wall of the road surface. A mounting plate is fixed to the top outer wall of the mounting columns. A second stepper motor is fixed to the inner wall of one end of the mounting plate. A connecting block is fixed to the output shaft of the second stepper motor. A rotating rod is fixed to one outer wall of the connecting block. A guide groove is opened on one outer wall of the rotating rod. A movable block is slidably connected to the inner wall of the guide groove. A moving mechanism is provided on the inner wall of the guide groove. A rotating shaft is rotatably connected to the bottom outer wall of the movable block through a damping rotating shaft. A monitoring probe is fixed to the bottom outer wall of the rotating shaft.

[0008] A gear is fixed to the outer wall of the rotating shaft, and a rack plate is fixed to the outer wall of one side of the rotating rod. The rack plate and the gear are meshed together.

[0009] Side support rods are fixed to the outer walls on both sides of the mounting column. A cavity is opened on one side of the outer wall of the side support rod. An infrared sensor is installed on the inner wall of the cavity. A transparent protective cover is fixed to the outer wall of the cavity.

[0010] Preferably, the inner wall of the mounting column is equipped with a controller, and the second stepper motor and the infrared sensor are electrically connected to the controller.

[0011] Furthermore: an L-shaped rod is fixed to the bottom outer wall of the rotating rod, and an L-shaped plate is fixed to one end of the L-shaped rod.

[0012] A further preferred embodiment: the moving mechanism includes a third stepper motor and a lead screw. The third stepper motor is fixed on the inner wall of one side of the guide groove. The lead screw is connected to the output shaft of the third stepper motor through a coupling. The inner wall of the movable block is connected to the outer wall of the lead screw through a thread. The third stepper motor is electrically connected to the controller.

[0013] As a preferred embodiment of the present invention, a set of lighting lamps is fixed on the top outer wall of the mounting plate.

[0014] As a further preferred embodiment of the present invention: a set of support blocks are fixed to one side of the outer wall of the mounting plate, and an elastic block is fixed to the outer wall of the support block.

[0015] As a further embodiment of the present invention: the inner wall of the mounting column is provided with a mounting groove, a fourth stepper motor is fixed on one side of the inner wall of the mounting groove, the output shaft of the fourth stepper motor is connected to a winding drum through a coupling, and a wire is wound on the outer wall of the winding drum.

[0016] Based on the aforementioned scheme: a wire groove is opened on the inner wall of the bottom of the mounting groove, a wire through hole is opened on the inner wall of one side of the mounting groove, a wire through hole is opened on one side of the winding roller, one end of the wire passes through the wire through hole and is connected to the monitoring probe, and the other end of the wire passes through the wire through hole and the wire groove and is connected to the power supply line and signal transmission line on the side of the road. The fourth stepper motor is connected to the controller.

[0017] Based on the aforementioned scheme, the preferred embodiment is as follows: a bracket is fixed to one side of the outer wall of the mounting column, a wind turbine is installed on the outer wall of the bracket, a first stepper motor is fixed to the outer wall of the side support rod, a brush plate is fixed to the output shaft of the first stepper motor, and the first stepper motor is electrically connected to the controller.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. When a vehicle is parked on one side of the transparent protective cover for an extended period, it indicates a traffic jam ahead. The controller then controls the second stepper motor to rotate the connecting block upwards by 90 degrees, making the rotating rod vertical. Subsequently, the controller controls the moving mechanism to move the movable block upwards, raising the height of the monitoring probe. When the gear on the outer wall of the rotating shaft moves to the rack plate side under the action of the movable block, it meshes with the rack plate, causing the rotating shaft to rotate to one side. When the movable block moves to the top of the rotating rod, the rotating shaft will rotate 180 degrees under the action of the gear, causing the lens of the monitoring probe to rotate in the opposite direction and clearly capture images of the congested area ahead. This allows traffic control personnel to understand the cause of the traffic congestion in advance through the images captured by the monitoring probe, enabling them to quickly take appropriate action and improve the efficiency of handling traffic congestion and accidents.

[0020] 2. When the entire monitoring probe moves away from the rack plate side under the action of the movable block, the monitoring probe will rotate back to the initial angle and monitor the traffic flow on that side of the road normally. When the movable block moves to the initial position under the action of the moving mechanism, the L-shaped plate at one end of the L-shaped rod will also abut against the outer wall of one side of the monitoring probe, thereby supporting and limiting the entire monitoring probe and preventing the monitoring probe from shaking when monitoring the road.

[0021] 3. When the controller controls the second stepper motor and the moving mechanism to drive the monitoring probe to rotate upward, it will simultaneously control the fourth stepper motor to drive the winding drum to rotate counterclockwise at a certain speed. The rotating winding drum will release the wire outward at a uniform speed, so that one end of the wire can be stably connected to the end of the continuously rising monitoring probe. When the controller controls the second stepper motor and the moving mechanism to drive the monitoring probe to reset, the fourth stepper motor drives the winding drum to rotate clockwise, and rewinds the released wire onto the winding drum, so that the monitoring probe can always be connected to the external power supply and signal transmission line through the wire when rotating up and down and moving.

[0022] 4. The controller will periodically control the first stepper motor to drive the brush plate to rotate a corresponding number of revolutions, thereby cleaning the outer wall of the transparent protective cover through the brush plate, avoiding the problem of excessive dust adhering to the outer wall of the transparent protective cover affecting the normal operation of the inner infrared sensor.

[0023] 5. After the vehicle starts moving normally, no vehicle will stay on the side of the transparent protective cover for an extended period of time. At this time, the controller will control the moving mechanism to move the movable block downwards and reset it. The rotating shaft will also rotate 180 degrees in the opposite direction under the meshing connection of the rack plate and the side support rod. Then, the controller will control the second stepper motor to drive the connecting block to rotate downwards by 90 degrees, so that the rotating rod as a whole rotates back to the side of the mounting plate, and the monitoring probe rotates back to the direction that can capture the front of the vehicle, so as to continue monitoring the road conditions and the moving vehicles.

[0034] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Example 1:

[0037] A smart traffic real-time monitoring device, such as Figure 1-9 As shown, the system includes a set of mounting columns 1 fixed to the top outer wall of the road surface 7. A mounting plate 12 is fixed to the top outer wall of the mounting column 1. A second stepper motor 14 is fixed to the inner wall of one end of the mounting plate 12. A connecting block 13 is fixed to the output shaft of the second stepper motor 14. A rotating rod 9 is fixed to one side outer wall of the connecting block 13. A guide groove 27 is opened on one side outer wall of the rotating rod 9. A movable block 26 is slidably connected to the inner wall of the guide groove 27. A moving mechanism is provided on the inner wall of the guide groove 27. A rotating shaft 21 is rotatably connected to the bottom outer wall of the movable block 26 through a damping rotating shaft. A monitoring probe 11 is fixed to the bottom outer wall of the rotating shaft 21.

[0038] A gear 20 is fixed to the outer wall of the rotating shaft 21, and a rack plate 22 is fixed to the outer wall of one side of the rotating rod 9. The rack plate 22 and the gear 20 are meshed together.

[0039] Side support rods 3 are fixed to the outer walls on both sides of the mounting column 1. A cavity is opened on one side of the outer wall of the side support rod 3. An infrared sensor is installed on the inner wall of the cavity. A transparent protective cover 5 is fixed to the outer wall of the cavity.

[0040] A controller is provided on the inner wall of the mounting column 1, and the second stepper motor 14 and the infrared sensor are electrically connected to the controller respectively;

[0041] Mounting posts 1 are installed on both sides of the road, but not on the same horizontal line. Side support rods 3 on both sides of the mounting posts 1 provide stable support. Meanwhile, an infrared sensor on one side of the transparent protective cover 5 detects vehicles parked on that side. When a vehicle is parked on the side of the transparent protective cover 5 for an extended period, it indicates traffic congestion ahead. At this time, the controller inside the mounting post 1 controls the second stepper motor 14 to rotate the connecting block 13 upwards by 90 degrees, thus making the rotating rod 9 vertical. Subsequently, the controller controls the moving mechanism to move the movable block 26 upwards, thereby improving monitoring efficiency. When the gear 20 on the outer wall of the rotating shaft 21 moves to one side of the rack plate 22 under the drive of the movable block 26, it will mesh with the rack plate 22, thereby driving the rotating shaft 21 to rotate to one side. When the movable block 26 moves to the top of the rotating rod 9, the rotating shaft 21 will rotate 180 degrees under the drive of the gear 20, causing the lens of the monitoring probe 11 to rotate in the opposite direction and clearly capture the area of ​​congestion in front of the road. This allows the traffic control personnel to understand the cause of the road congestion in advance through the images captured by the monitoring probe 11, thereby quickly taking corresponding actions and improving the efficiency of handling road congestion and accidents.

[0042] After the traffic congestion and accident handling are completed and the vehicles are driving normally, no vehicle will stay on the side of the transparent protective cover 5 for a long time. At this time, the controller will control the moving mechanism to drive the movable block 26 to move downward and reset. The rotating shaft 21 will also rotate 180 degrees in the opposite direction under the meshing connection of the rack plate 22 and the side support rod 3. Then the controller will control the second stepper motor 14 to drive the connecting block 13 to rotate downward 90 degrees, so that the rotating rod 9 will rotate back to the side of the mounting plate 12, and the monitoring probe 11 will rotate back to the direction that can capture the front of the vehicle, so as to continue to monitor the road conditions and the vehicles.

[0043] like Figure 4-5 As shown, an L-shaped rod 18 is fixed to the bottom outer wall of the rotating rod 9, and an L-shaped plate 16 is fixed to one end of the L-shaped rod 18. When the entire monitoring probe 11 moves away from the rack plate 22 under the drive of the movable block 26, the monitoring probe 11 will rotate back to the initial angle and monitor the traffic flow on that side of the road normally. When the movable block 26 moves to the initial position under the drive of the moving mechanism, the L-shaped plate 16 at one end of the L-shaped rod 18 will also abut against the outer wall of one side of the monitoring probe 11, thereby supporting and limiting the entire monitoring probe 11 and preventing the monitoring probe 11 from shaking when monitoring the road.

[0044] like Figure 4-7As shown, the moving mechanism includes a third stepper motor 30 and a lead screw 29. The third stepper motor 30 is fixed to one inner wall of the guide groove 27. The lead screw 29 is connected to the output shaft of the third stepper motor 30 through a coupling. The inner wall of the movable block 26 is connected to the outer wall of the lead screw 29 through a thread. The third stepper motor 30 is electrically connected to the controller. The controller can control the third stepper motor 30 to drive the lead screw 29 to rotate forward and backward, thereby driving the movable block 26 to move back and forth as a whole, thereby adjusting the height and position of the monitoring probe 11.

[0045] like Figure 1-2 As shown, a set of lighting lamps 10 are fixed on the top outer wall of the mounting plate 12; the lighting lamps 10 can illuminate the road conditions around the monitoring device.

[0046] like Figure 2 As shown, a set of support blocks 15 are fixed to one side of the outer wall of the mounting plate 12, and an elastic block 19 is fixed to the outer wall of the support block 15; the support block 15 can support and limit the rotation rod 9 that has rotated to one side of the mounting plate 12, thereby improving the overall stability of the rotation rod 9.

[0047] like Figure 1-5 As shown, the inner wall of the mounting column 1 has a mounting groove 24, and a fourth stepper motor 32 is fixed on one side of the inner wall of the mounting groove 24. The output shaft of the fourth stepper motor 32 is connected to a winding drum 23 through a coupling. A wire 28 is wound on the outer wall of the winding drum 23.

[0048] The mounting groove 24 has a wire groove 25 on its bottom inner wall, a wire through-hole 8 on one side of its inner wall, and a wire through-hole 31 on one side of its winding roller 23. One end of the wire 28 passes through the wire through-hole 8 and connects to the monitoring probe 11, while the other end of the wire 28 passes through the wire through-hole 31 and the wire groove 25 and connects to the power supply line and signal transmission line on the side of the road. The fourth stepper motor 32 is connected to the controller. When the controller controls the second stepper motor 14 and the moving mechanism to rotate the monitoring probe 11 upwards, it simultaneously controls the fourth stepper motor 32 to rotate the winding roller 23 upwards. Rotating counterclockwise at a certain speed, the winding drum 23 will release the wire 28 outward at a uniform speed, so that one end of the wire 28 can be stably connected to one end of the continuously rising monitoring probe 11. When the controller controls the second stepper motor 14 and the moving mechanism to drive the monitoring probe 11 to reset, it will simultaneously control the fourth stepper motor 32 to drive the winding drum 23 to rotate clockwise, so that the released wire 28 is rewound onto the winding drum 23, so that the monitoring probe 11 can always be connected to the external power supply and signal transmission line through the wire 28 when rotating up and down and moving.

[0049] In this embodiment, the controller is a commercially available control device that can receive and process sensor signals and control stepper motors. All of these are mature existing technologies, and the specific working principle will not be elaborated here. The infrared sensor is a commercially available infrared sensor with object occlusion detection function.

[0050] In this embodiment, the infrared sensor located on one side of the transparent protective cover 5 can detect vehicles parked on one side. When a vehicle is parked on one side of the transparent protective cover 5 for a long time, it indicates that there is congestion on the road ahead. At this time, the controller located inside the mounting column 1 will control the second stepper motor 14 to drive the connecting block 13 to rotate upward by 90 degrees, so that the rotating rod 9 is vertically raised. Then the controller controls the moving mechanism to drive the movable block 26 to move upward, thereby raising the height of the monitoring probe 11. When the gear 20 on the outer wall of the rotating shaft 21 moves to the side of the rack plate 22 under the drive of the movable block 26, it will mesh with the rack plate 22, thereby driving the rotating shaft 21 to rotate to one side. When the movable block 26 moves to the top of the rotating rod 9, the rotating shaft 21 will rotate 180 degrees under the drive of the gear 20, so that the lens of the monitoring probe 11 rotates to the opposite direction and clearly captures the area of ​​congestion in front of the road, so that the corresponding traffic control personnel can understand the cause of the road congestion in advance through the image captured by the monitoring probe 11.

[0051] After the traffic congestion and accident handling are completed and vehicles resume normal operation, no vehicle will linger on the side of the transparent protective cover 5 for an extended period. At this time, the controller will control the moving mechanism to move the movable block 26 downward and reset it. The rotating shaft 21 will also rotate 180 degrees in the opposite direction under the meshing connection of the rack plate 22 and the side support rod 3. Subsequently, the controller will control the second stepper motor 14 to drive the connecting block 13 to rotate downward by 90 degrees, thereby allowing the rotating rod 9 to rotate back to the side of the mounting plate 12, and allowing the monitoring probe 11 to rotate back to the direction where it can capture the front of the vehicle, thus continuing to monitor the road conditions and vehicles.

[0052] Example 2:

[0053] A smart traffic real-time monitoring device, such as Figure 2-3As shown, this embodiment makes the following improvements based on embodiment 1: A bracket 17 is fixed to one side of the outer wall of the mounting column 1, a wind turbine generator 2 is installed on the outer wall of the bracket 17, a first stepper motor 4 is fixed to the outer wall of the side support rod 3, a brush plate 6 is fixed to the output shaft of the first stepper motor 4, and the first stepper motor 4 is electrically connected to the controller; the wind turbine generator 2 can generate electricity using the traffic flow generated by cars on the road and natural wind to power some equipment on the monitoring device. At the same time, the controller will periodically control the first stepper motor 4 to drive the brush plate 6 to rotate a corresponding number of revolutions, thereby cleaning the outer wall of the transparent protective cover 5 through the brush plate 6, avoiding the problem of excessive dust adhering to the outer wall of the transparent protective cover 5 affecting the normal operation of the inner infrared sensor.

[0054] In this embodiment, the controller periodically controls the first stepper motor 4 to drive the brush plate 6 to rotate a corresponding number of revolutions, thereby cleaning the outer wall of the transparent protective cover 5 through the brush plate 6.
